Bake a Devil's Food Cake according to package directions. DO NOT COOL. When right out of the oven, poke holes with the end of a wooden spoon. Drizzle 1 can of condensed milk into the holes. Warm the jar of hot fudge and also drizzle into the holes. Spread any extra on top of the cake. Sprinkle chopped, toasted pecans on top of the hot fudge layer. When cake is cool enough, spread the whipped topping over the top of cake. Refrigerate. Just before serving, so they don't get soggy, sprinkle half a package of Heath Bits over top of cake. ( You may have a desire for a cigarette afterwards.)
